It is a well-known fact that steel is an important material used in many engineering applications, such as in the automotive industry, construction and machinery industries. In addition, desulfurization is a crucial process in steelmaking, since sulfur is an undesirable chemical element in steel’s composition. Although it results in better quality steel, it leads to a non-green slag that if not handled correctly may harm the environment. This study has the goal of discussing the process of desulfurization of hot metal in torpedo cars using CaC2 (calcium carbide) based desulfurizer and presenting the introduction and the possibility of reusing the slag in other green applications. Desulfurization is a pre-treatment that removes the sulfur located in hot metal throughout the chemical reaction of the desulfurizer injected in molten metal inside of the torpedo car.Therefore, after collecting the desulfurization slag from a local industrial process, the analysis of its properties starts, which was conducted using proper tools such as Scanning Electron Microscopy and also using X-Ray Diffraction and Fluorescence Analysis. In such manner, there will be a complete description of the slag's characteristics, which will lead to discussions about making the desulfurization’s slag disposal a greener alternative, such as implementing other uses like agriculture.
